BACKGROUND Loss of hearing is a common problem that can result from noise, aging, disease, and heredity. Approximately 28 million Americans have significant hearing loss, and of that group work for only hearing populations and have yet to group, almost six million are profoundly deaf [17].

  • Grasping Gestures: Gesturing with Physical Artifacts
    Artificial Intelligence for Engineering Design, Analysis and Manufacturing (2011), 25, 255–271. # Cambridge University Press 2011 0890-0604/11 $25.00 doi:10.1017/S0890060411000072 Grasping gestures: Gesturing with physical artifacts 1 2 ELISE VAN DEN HOVEN AND ALI MAZALEK 1User-Centered Engineering Group, Industrial Design Department, Eindhoven University of Technology, Eindhoven, The Netherlands 2Synaesthetic Media Lab, Digital Media Program, Georgia Institute of Technology, Atlanta, Georgia, USA (RECEIVED July 19, 2010; ACCEPTED October 6, 2010) Abstract Gestures play an important role in communication. They support the listener, who is trying to understand the speaker. How- ever, they also support the speaker by facilitating the conceptualization and verbalization of messages and reducing cog- nitive load. Gestures thus play an important role in collaboration and also in problem-solving tasks. In human–computer interaction, gestures are also used to facilitate communication with digital applications, because their expressive nature can enable less constraining and more intuitive digital interactions than conventional user interfaces. Although gesture re- search in the social sciences typically considers empty-handed gestures, digital gesture interactions often make use of hand- held objects or touch surfaces to capture gestures that would be difficult to track in free space. In most cases, the physical objects used to make these gestures serve primarily as a means of sensing or input. In contrast, tangible interaction makes use of physical objects as embodiments of digital information. The physical objects in a tangible interface thus serve as representations as well as controls for the digital information they are associated with. Building on this concept, gesture interaction has the potential to make use of the physical properties of hand-held objects to enhance or change the function- ality of the gestures made.

  • User Interaction in Hybrid Multi-Display Environments
    User Interaction in Hybrid Multi-Display Environments Hrvoje Benko Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2007 © 2007 Hrvoje Benko All Rights Reserved ABSTRACT User Interaction in Hybrid Multi-Display Environments Hrvoje Benko This dissertation presents the design, implementation, and evaluation of novel pointer-based and gesture-based interaction techniques for multi-display environments (MDEs). These techniques transcend the constraints of a single display, allowing users to combine multiple displays and interaction devices in order to benefit from the advan- tages of each. First, we introduce a set of pointer warping techniques, which improve existing mouse pointer interaction in an MDE, by allowing users to instantaneously relocate the cursor to an adjacent display, instead of traversing the bezel. Formal evaluations show significant improvements in user performance when compared to standard mouse be- havior. Next, we focus on a particular kind of MDE, in which 3D head-worn augmented re- ality displays are combined with handheld and stationary displays to form a hybrid MDE. A key benefit of hybrid MDEs is that they integrate and utilize the 3D space in which the 2D displays are embedded, creating a seamless visualization environment. We describe the development of a complex hybrid MDE system, called Visual Interac- tion Tool for Archaeology (VITA), which allows for collaborative off-site analysis of archaeological excavation data by distributing the presentation of data among several head-worn, handheld, projected tabletop, and large high-resolution displays. Finally, inspired by the lack of freehand interactions for hybrid MDEs, we designed gestural techniques that address the important issues of interacting across and within 2D and 3D displays.

    Hand-and-Finger-Awareness for Mobile Touch Interaction using Deep Learning Von der Fakultät für Informatik, Elektrotechnik und Informationstechnik und dem Stuttgart Research Centre for Simulation Technology der Universität Stuttgart zur Erlangung der Würde eines Doktors der Naturwissenschaften (Dr. rer. nat.) genehmigte Abhandlung Vorgelegt von Huy Viet Le aus Nürtingen Hauptberichter: Prof. Dr. Niels Henze Mitberichter: Prof. Antti Oulasvirta Mitprüfer: Jun.-Prof. Dr. Michael Sedlmair Tag der mündlichen Prüfung: 28.03.2019 Institut für Visualisierung und Interaktive Systeme der Universität Stuttgart 2019 2 Zusammenfassung Mobilgeräte wie Smartphones und Tablets haben mittlerweile Desktop Compu- ter für ein breites Spektrum an Aufgaben abgelöst. Nahezu jedes Smartphone besitzt einen berührungsempfindlichen Bildschirm (Touchscreen), welches die Ein- und Ausgabe zu einer Schnittstelle kombiniert und dadurch eine intuitive Interaktion ermöglicht. Mit dem Erfolg sind Anwendungen, die zuvor nur für Desktop Computer verfügbar waren, nun auch für Mobilgeräte verfügbar. Dieser Wandel steigerte die Mobilität von Computern und erlaubt es Nutzern dadurch Anwendungen auch unterwegs zu verwenden. Trotz des Erfolgs von Touchscreens sind traditionelle Eingabegeräte, wie Tastatur und Maus, aufgrund ihrer Eingabemöglichkeiten immer noch überlegen. Eine Maus besitzt mehrere Tasten, mit denen verschiedene Funktionen an dersel- ben Zeigerposition aktiviert werden können. Zudem besitzt eine Tastatur mehrere Hilfstasten, mit denen die Funktionalität anderer Tasten vervielfacht werden. Im Gegensatz dazu beschränken sich die Eingabemöglichkeiten von Touchscreens auf zweidimensionale Koordinaten der Berührung. Dies bringt einige Herausfor- derungen mit sich, die die Benutzerfreundlichkeit beeinträchtigen. Unter anderem sind Möglichkeiten zur Umsetzung von Kurzbefehlen eingeschränkt, was Sheider- mans goldene Regeln für das Interface Design widerspricht. Zudem wird meist nur ein Finger für Eingabe verwendet, was die Interaktion verlangsamt.

    MITSUBISHI ELECTRIC RESEARCH LABORATORIES http://www.merl.com DiamondTouch SDK:Support for Multi-User, Multi-Touch Applications Alan Esenther, Cliff Forlines, Kathy Ryall, Sam Shipman TR2002-48 November 2002 Abstract DiamondTouch is a multi-touch input technology that supports multiple, simultaneous users; it can distinguish who is touching where. We present the DiamondTouch SDK; it provides sup- port for the development of applications that utilize DiamondTouch s capabilities to implement computer-supported collaboration and rich input modalities (such as gestures). Our first demo illustrates the basic utilities and functionality of our system. Our second demo, a multi-user map application, highlights DiamondTouch s ability to sup-port input from multiple, simultane- ous users and exploits Di-amondTouch s ability to identify the owner of each touch. Our third demo illustrates DiamondTouch s ability to run with existing applications by providing a mouse emulation mode. DiamondTouch is well-suited to shared-display applications. It is suitable for front-projected video of the computer display, which facilitates direct manipulation of user interface elements and provides a shared focus of attention for collab-orating users. Possible applications include command-and-control command posts, control rooms, business or technical meetings, and a variety of casual applications in the home, at schools, and in retail settings.
